To CLZZ whom it may concern.-

Be it known that I, VILLIAM SCOTT MOR- TON, a subject of thc Queen of Great Britain and Ireland, residing at Edinburgh, in the county of Mid-Lothian, Scotland, have invented an Improvement in the Methods of Embossing Canvas i'or Decorating lValls or other Surfaces, (for which I have obtained British patents dated November 18, 1881, No. 15,161, and dated December 2, 1885, No.14,793; French patent dated September 22, 1885, No. 171,281, and Belgian patent dated September 23, 1885, No. 70281,) of which the following` is a speciication.

This invention has t'or its object to improve and cheapen the manufacture of embossed canvas for decorative purposes, and in carrying it out there are provided molds for producing the raised ornamental devices on the canvas. These molds may consist of plates ot' metal or other suitable material formed by casting from patterns or otherwise and placed on a metal chest or casing, or the mold may be tormed in vl he top plate of the metal chest. Instead ot making the molds flat, theymay take the t'orm of a hollow metal cylinder. The molds arc heated by means ot steam or other hot tluid. The canvas is tlrst prepared b v boiling or steeping in boiling water, and subsequently sleeping in hot size and wringing or squeezing out to a suitablc extent. lt is then applied to the molding-surfaces and worked into all the cavities of thc mold by means ot' brushes 0r pads. A backing of 'pasted paper is then applied and the heat ol' the mold causes the canvas to rapidly stiften and dry, so as to retain the embossed ett'ect. The brushes or pads maybe worked by hand or b y apparatus of the kind described in the specification ot the United States patent granted to the present applicant, No. 294,257, dated lleln'nary 26, 1881-.

Figure l ot' the accompanying drawings is a perspective (-levation ol' my improved embossing machine as made with a flat moldplate, Fig. 2 heilig a transverse section ot the mold-plate and steain-chest, and Fig. 3 a transverse section of a modiiication of the mold-plate and steam-chest.

In the arrangement shown in Figs. 1 and 2 a plate, 8, of metal or other suitable material., is formed by casting from patterns or otherwise shaping it so as to serve for a mold for producing raised ornamental devices 0n the canvas, the design being n intaglio in the surface of the plate. This mold-plate 8 is placed on a shallow metal chest or casing, 9, to which it is secured by bolts. Branch pipes 10 enter the casing, and are connected to a central horizontal pipe, 11, fitted with a dripcock, 12. This pipe 11 extends to one end of the apparatus and has connected to its outer end two horizontal transverse pipes, 13 14:, tted with stop-valves 15 16, the outer ends of the pipes 1314 being connected to two vertical pipes, 17 18. Steam for heating the casing O enters by the pipe 17, its admission being regulated by the stop-valve 15, and water for cooling the casing enters by pipe 18, the stop-valve 16 regulating its admission. The mold-plate 8 is provided with cocks 19 for the escape of air, and is slightly inclined from the end at which the stop-valves 15 16 are placed toward a corner at the opposite end, where there is fitted a vertical dischargepipe, 20, having at its lower end a drip-cock, 2l. The discharge-pipe 2O is connected by a short horizontal pipe to two vertical pipes, 22 28, having stop-valves 24 25. The lower pipe, 22, and val ve 21 are for the discharge of steam, while the upper pipe, 23, and valve 25 are for the discharge ot' water, and they extend sufiiciently high to insure the chest 9 being' com-l pletel)T lilled with the cooling-liquid. The outer ends of the pipes 22 are connected to horizontal pipes 26, which communicate with a vertical discharge-pipe, 27.

Fig. 3 shows the chest 9 as made in one piece andthe mold-plate 8 laid on the top ol it.

When the canvas has been sized, as hereinbelore described, it is laid on thc mold-plate and worked into all the cavities by brushes or beaters, the deeper cavities being packed with paper-pulp, papier-mache, or other suitable substance, and a paper-backing is pasted over the whole. After the moistened and sized canvas has been worked into the cavi-
